The Actinic keratoses are very common precancerous lesions of the skin exposed to the sun and can be worst in aggressive squamous cell carcinomas with metastasis potential. The incidence of light on people ever increasing particularly in areas with high exposure to ultraviolet radiation. Therefore consists prevention of squamous cell carcinoma in the early treatment of actinic keratosis. It is important to implement an effective and easy method of treatment.

The non Melanocytic skin cancers, namely basal and squamous cell carcinoma are now the most common malignant neoplasms.

Workaround actinic keratoses

The most common methods for the treatment of actinic keratoses are:



chemical peeling,


topical chemotherapy and,

last photodynamic therapy.

Photodynamic treatment involves a treatment of choice for actinic keratosis. It has good cost effectiveness and is established as a minimally invasive alternative to contrast the invasive techniques, in particular those requiring concomitant treatment of extensive areas of skin with multiple recurrent lesions.


What proportion is the treatment successfull

Topical photodynamic therapy offers a high cure rate (generally 73 to 100% of actinic keratoses) with excellent aesthetic results, better than other conventional treatments, less recovery time, and are generally well tolerated by patients. It is based on a photochemical reaction caused by the use of a light wave source capable of activating sensitive molecules, photosensitive substances, which selectively retained by noxious tissues, leading to the formation of cytotoxic oxygen product resulting in damage and death of cells.
